Abstract
The present disclosure is directed to an acoustic transducer configured to detect a sound wave according to changes in capacitances between a vibrating electrode and a fixed electrode. At least one of the vibrating electrode and the fixed electrode being divided into a plurality of divided electrodes, and the plurality of divided electrodes outputting electrical signals. The disclosure includes a digital interface circuit coupled to the divided electrodes. The circuit includes a recombination stage, which supplies a mixed signal by combining the first digital processed signal and the second digital processed signal with a respective weight that is a function of a first level value of the first processed signal. An output stage is included, which supplies, selectively and alternatively, a first processed signal, a second processed signal, or a mixed signal.
